## Ontology Info

| Field | Value |

| Acronyme | PREO |
| Description | The Presence Ontology is a systematic vocabulary of terms with defined relationships that models the encounters taking place every day among providers, patients, and family members or friends in environments such as hospitals and clinics. The Presence Ontology provides a conceptual model for the human experience in medicine. This is a preliminary approach, but further use of methods we have developed here may aid in providing clarity and consensus to topics in healthcare. The ontology is also a model for interdisciplinary collaboration, as it was developed in conjunction with experts from bioinformatics, medicine, anthropology, business, and communication sciences through multiple iterative stages. |
